Subscription Policy

Monthly membership renewal

By enrolling in a SlimTheory membership, you authorize SlimTheory to charge your selected payment method automatically each month until the membership is paused or canceled.

Your recurring billing date is the calendar day on which you first enroll. For example, if you enroll on the 9th, your membership will renew automatically on the 9th of each month.

Memberships are personal, may not be transferred to another person and may not be shared.

Billing dates

Your recurring billing date appears in your membership account. To be included in the current month’s shipment period, your payment must be successfully completed no later than the 15th of that month.

You may request a different recurring billing date that falls on or before the 15th. Billing-date changes must be requested before the upcoming payment is processed.

Monthly shipment eligibility

SlimTheory monthly orders generally ship during the third week of each month, beginning on the third Monday.

Shipment timing is based on successful payment by the monthly cutoff—not the date on which you originally enrolled.

Failed or late payments

You are responsible for maintaining a valid payment method and ensuring that sufficient funds are available on your billing date.

If a payment fails, you may update your payment method and retry the payment. Payments successfully completed after the 15th are not guaranteed to be included in that month’s shipment period. If SlimTheory is unable to ship your medication for that month, the late payment will be refunded in full.

SlimTheory cannot guarantee a current-month shipment when payment is completed after the monthly cutoff.

Membership and program changes

Medication, dose and program changes are handled only during SlimTheory’s designated monthly dosage consultation period.

Members will be notified when the consultation period opens and must submit the appropriate dosage consultation form before the stated deadline. Requests submitted by email or outside the consultation period are not guaranteed to be reviewed or applied to the upcoming shipment.

Approved changes will be reflected in the applicable monthly order.

Pausing your membership

Active members may pause their own membership directly from the member portal. Sign in, open your membership controls and confirm the pause before the next monthly order is processed. You do not need to email SlimTheory to complete a standard pause.

A confirmed pause stops future eligible recurring charges and shipments. If the pause is completed after payment has been collected but before medication has shipped, the payment may be refunded for that billing cycle. Once medication has shipped, the order cannot be canceled, returned or refunded.

Members who pause for more than one billing cycle may need to restart at a lower dose when they return. The appropriate restart dose will depend on the medication previously used, the prior dose and the length of the pause.

Canceling your membership

You may cancel your membership at any time before your next order has been processed and shipped. Cancellation stops future recurring charges but does not automatically reverse an order that has already shipped.

If payment has been collected but medication has not yet shipped, you may request cancellation and a refund for that billing cycle.

Refunds and returns

Because medication cannot be returned or reused after shipment:

• A full refund may be requested when payment has been collected but medication has not yet shipped.
• Orders that have already shipped are not eligible for return or refund.
• Refusing delivery or failing to retrieve a delivered package does not make the order eligible for a refund.
• Shipping-address errors, missing packages and replacement requests are handled under SlimTheory’s Missing Packages and Medication Replacement Policy.

Payment methods

SlimTheory accepts major debit and credit cards. Eligible customers may also use available pay-later options, including Afterpay, Klarna and Zip.

SlimTheory does not accept insurance, Health Savings Account (HSA) funds or Flexible Spending Account (FSA) funds.

Approval, payment schedules, fees and account management for pay-later services are controlled by the individual payment provider.

Questions or requests

Members can pause their own membership directly in the member portal. Other membership changes, billing-date changes, cancellations and refund requests should also be submitted through the portal whenever possible.
